Background: The study was conducted at a Producer Gas Plant � old and new plants located in a giant public sector company. The various hazards like coal dust, carbon monoxide and the noise levels were studied in selected work stations. Aim: The object of this study is to identify and assess the prevailing occupational hazards in the plant. It is to assess the work room air and near the ambit of the workers, comparing the measured values with the recommended OELs and recommends engineering and administrative control measures and to assess the effectiveness of the implemented engineering measures. Materials and Methods: Employees of various levels were included in the sampling procedure. The follow up studies were carried out to evaluate the effectiveness of the recommended implementations by assessing the work exposures in both the plants. Statistical Analysis: Plant wise distribution analysis was done on the compiled database. The statistical tools IBM SPSS version-20 and the Mini-Tab Version-16 were used for the analysis of the data. One way ANOVA F Test and Paired t test were done to assess the effectiveness and the significance. Results: About 40 samples were collected with the 5% level of significance and 95% confidence interval level. Three work environmental factors were analyzed for the influence of risk to employees. The effectiveness of the measures was determined. Conclusions and Implications: This study has demonstrated that the work environmental factors were varying based on the operational variations such as plant load, air movement and other environmental factors and recommendations were given to mitigate those predominant factors to the management. It is concluded that there is a significant level of effectiveness (p<0.05) in the implemented control measures at by measuring the quantitative exposures to the pollutants in the work room air.
